Remove white papery skin from garlic head (do not peel or separate cloves). Wrap head in foil. Arrange yellow beets on a large sheet of foil; wrap tightly. Repeat procedure with red and striped beets.
Bake garlic and beets at 350 for 1 hour or until beets are tender; cool 10 minutes. Separate garlic cloves; squeeze to extract garlic pulp. Discard skins.
Combine garlic pulp, oil, and next 6 ingredients (through pepper) in a small bowl, stirring with a whisk.
Place kale in a large bowl.
Heat a medium skillet over medium heat; add bacon. Cook 5 minutes or until crisp, stirring occasionally. Increase heat to high. Stir in garlic mixture; remove from heat.
Pour hot bacon mixture over kale, tossing to coat.
